EPPO RNQP

NAME OF THE ORGANISM: Tobacco rattle virus (TRV000)

GENERAL INFORMATION ON THE PEST

Name as submitted in the project specification (if different to the preferred name):

Pest category:

Viruses and viroids

1- Identity of the pest/Level of taxonomic listing:

Is the organism clearly a single taxonomic entity and can it be adequately distinguished from other entities of the same rank?

Yes

Is the pest defined at the species level or lower?:

Yes

Can listing of the pest at a taxonomic level higher than species be supported by scientific reasons or can species be identified within the taxonomic rank which are the (main) pests of concern?

Not relevant: Seed potato sector, Ornamental sector

Is it justified that the pest is listed at a taxonomic rank below species level?

Not relevant

Conclusion:

Not evaluated: Seed potato sector, Ornamental sector

2 – Status in the EU:

Is this pest already a quarantine pest for the whole EU?

Presence in the EU:

Yes

List of countries (EPPO Global Database):

Austria (2004); Belgium (2004); Bulgaria (2004); Czech Republic (2004); Denmark (2004); Finland (2011); France (2004); Germany (2004); Greece (2004); Hungary (2004); Italy (2004); Latvia (2004); Lithuania (2004); Netherlands (2015); Poland (2014); Sweden (2014); United Kingdom (2004)

Conclusion:

Justification (if necessary):

Data of the presence of this pest on the EU territory are available in EPPO Global Database (https://gd.eppo.int/).

HOST PLANT N°1: Gladiolus (1GLAG) for the Ornamental sector.

CONCLUSION ON THE STATUS:

Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination was not identified by the experts of the ornamental SEWG as being a candidate for the RNQP status with specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the EU Marketing Directives for ornamentals.

HOST PLANT N°2: Lilium (1LILG) for the Ornamental sector.

CONCLUSION ON THE STATUS:

HOST PLANT N°3: Narcissus (1NARG) for the Ornamental sector.

CONCLUSION ON THE STATUS:

HOST PLANT N°4: Solanum tuberosum (SOLTU) for the Seed potato sector.

Origin of the listing:

PM 4/28 (1)

Plants for planting:

Plants intended for planting of nuclear stock, other than [true] seeds

3 - Is the pest already listed in a PM4 standard on the concerned host plant?

Yes

Conclusion:

Qualified

Justification (if necessary):

Experts agreed that the nuclear stock should be tested or derived from mother plants which have been tested for this virus.

CONCLUSION ON THE STATUS:

Recommended for listing as an RNQP, based on EPPO PM 4 Standard, only for the nuclear stock.

8 - Tolerance level:

Is there a need to change the Tolerance level:

Yes

Proposed Tolerance levels:

Zero tolerance, only for nuclear stock.

9 - Risk management measures:

Is there a need to change the Risk management measure:

Yes

Proposed Risk management measure:

Nuclear stock should be tested or derived from mother plants which have been tested for Tobacco rattle virus.
